Washington (CNN) – As President Donald Trump huddled in the Oval Office on Friday with Kim Jong Un’s right-hand man, he was accompanied by only one other US official: Secretary of State Mike Pompeo. Absent was the administration’s most vocal North Korea hawk, national security adviser John Bolton.

The White House insists the meeting was always intended to remain small. But the tableau reflected deeper rifts among Trump’s national security team and a new reality as the President prepares for his historic meeting with Kim next week in Singapore: the voices advocating most forcefully to tighten the noose on Pyongyang have been sidelined as Trump seeks out a history-making handshake.

Escalating feud

Furious after Bolton raised the so-called “Libya” model to describe US intentions in North Korea — with its suggestion of a grisly death for a dictator who relinquishes his nuclear arms — Trump has publicly walked back his national security adviser’s rhetoric as he works to ensure his summit talks with Kim proceed. In doing so, he’s dramatically lowered the bar for his face-to-face session with Kim, who has made no concrete commitments toward abandoning his nuclear arsenal.

Pompeo told Trump it would be “counterproductive” to allow Bolton to attend the Oval Office meeting with visiting North Korean official Kim Yong Chol, two people familiar with the matter said, citing an escalating feud between the top diplomat and Bolton. The simmering tensions between two of the President’s top foreign policy advisers reached a boiling point after Bolton went on television last month and cited the Libya model when talking about North Korea abandoning its nuclear program — and in doing so, also raising the specter of Libya’s subsequent invasion and its leader’s brutal murder.

North Korea reacted furiously, lambasting Bolton in a statement. It revived long-held criticism from the regime, most notably in 2003 when North Korean state media described Bolton as “human scum and a bloodsucker” during the Bush administration.

But the remarks about Libya also infuriated Pompeo, who angrily confronted Bolton in a heated conversation at the White House.

“There has been considerable tension between them ever since,” a person familiar with the West Wing confrontation said.

[…]Trump has given his secretary of state, whom he views as intelligent and charismatic, considerable leeway on North Korea — including following his lead and keeping Bolton at arm’s length from the negotiations. Even as the Libya comments from Bolton and Pence prompted angry reactions from Pyongyang — which, in turn, led to Trump canceling the summit — Pompeo continued on his diplomatic push with the North Koreans, eventually meeting Kim’s envoy in New York last week and smoothing the way for the summit to be rescheduled.

White House chief of staff John Kelly has remained in line with Pompeo, and has come to rely on his ability to guide the President, an official said. Kelly greeted Kim Jong Chol at the White House diplomatic entrance on Friday and escorted him to the Oval Office.

Pompeo views Bolton skeptically, two people familiar with their relationship say, and doesn’t trust his motives on North Korea. The two men barely knew each other before Bolton’s arrival as national security adviser, but Pompeo has grown to dislike his approach and believes he is “trying to advance his own agenda,” one official said.

[…] Trump continues to have broad faith in Bolton, people familiar with the matter said, despite his displeasure at the Libya comments. But on the issue of North Korea, the President is siding for now with Pompeo, who helped launch the diplomatic overture to Pyongyang when he was serving as CIA director. It’s an open question, however, how long that may last, given how rapidly aides can rise and fall in Trump’s eye and his insistence upon relying on his own instincts in high-stakes negotiations.

In recent days, Trump has told advisers that decades of conventional thinking on North Korea have failed, and that his own gut will guide him as he prepares for the audacious diplomatic opening with the young and unpredictable Kim. He’s sought to heighten anticipation around the summit, which he views as a major historic milestone. And he’s worked to soften the harsher rhetoric of his aides, including walking back Bolton and Pence’s comments about Libya during remarks in the Oval Office last month.

[…] people familiar with the summit planning now say there is little expectation Trump will emerge from his meeting with Kim having secured the type of historic, detailed commitment on denuclearization that officials once said was a prerequisite for the talks.

Instead, Trump and his aides have suggested the most concrete product of the June 12 encounter could be a peace agreement formally ending the Korean War — a far cry from the commitment to immediate denuclearization that the administration once insisted would be required for Trump to come to the table.

Now, the most some aides are hoping for is a broad declaration from Kim that he’s open to getting rid of his weapons, with the work of securing specific commitments from the North Korean regime handed off to aides for a process that experts predict could take years.

“I never said it goes in one meeting. I think it’s going to be a process,” Trump said on Friday. “But the relationships are building, and that’s a very positive thing.”

It’s good they backed off the total denuclearization talk. Kim’s not going to give up his nukes if he’s being threatened with the Gaddafi treatment as that would be suicidal.

These are hugely positive developments and show Trump and Pompeo, unlike Bolton, are serious about making a deal.
